9.5.7.4Power Manager Wake-Up Enable Register (PWER)

The following table shows the location of all wake-up interrupt enable bits in the PWER. For a GPIO to serve as a wake-up source, it must be programmed as an input in the GPDR. When a fault condition is detected in the VDD_FAULT or BATT_FAULT pins, this register is set to hexadecimal 0000 0003, enabling only GP<1,0> as wake-up sources. This register is also set to this value on hard reset (nRESET asserted). For reserved bits, writes are ignored and reads return zero.
